REFRIGERATING-MACHINE. 7

Application filed June 22, 1914. Serial No. 846,708.

To all whom it may concern:

Be it known that we, WILLIAM 1. Bonnie and CHARLES R. SOLOMON, citizens of the United States, residing in the city of Springfield, county of Greene, and State of Missouri, have invented a certain new and useful Improvement in Refrigerating-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to refrigerating machines, and particularly to the compressor and condenser that form part of such machines.

One object of our invention is to provide a compact, self-contained refrigerating machine in which the compressor and condenser are combined as a single unit, thus producing a small, compact machine that is practicable for household use.

Another object is to provide a self-contained refrigerating machine in which the condenser forms a permanent part of the base on which the compressor is mounted, the condensingchamber being formed by a drum-shaped member arranged inside of the base and spaced awayfrom the walls of same so as to form a watenjacket that surrounds the condensing chamber.

Another object is to provide a machine of the character described in which the condensing chamber also serves as a receiver for the condensed liquid.

Another object is to provide a serviceable refrigerating machine of simple construction that comprises few parts? and which can be manufactured at a low cost.

Other objects and desirable features of our invention will be l'rereinafter pointed out.

Briefly described, our improved. machine consists of a hollow base, a compressor mounted on said base and provided with a piston which controls the admission of gas through one or more ports forn'ied in the side wall of the cylinder, and a drum-shaped member arranged inside of the base to form a condensing chamber and spaced away from the base so as to form a water-jacket for the condensing chamber, the compressor, of course, being provided with a dischange valve thato'pens automatically so as to permit the compressed gas to flow from the cylinder of the compressor into the condensing chamber wherein it is condensed or 'con' verted into a liquid state.

Figure l of the drawings is a front elevational view of a refrigerating machine constructed in accordance with our invention. Fig. 2 is a vertical longitudinal sectional view of said machine. Fig. 3 is a vertical transverse sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is a horizontal secand Fig. 5 is a vertical transverse sectional View of the condenser taken on the line 5-5 of Fig. 2, looking in the direction indicated by the arrow.

Referring to the drawings which illustrate the preferred form of our invention, A designates tlie base of the machine which is a hollow member of any preferred cross-seetional shape and provided with legs or feet 1 so as to enable it to be securely connected to a foundation, not shown. A compressor B is mounted on the base A in an upright position, and a hollow drum-shaped member C is-arranged inside of the base A and spaced away from the walls thereof, as shown in ldigs. 2 and 3, so as to form a condensing chamber.

Instead of equipping the piston 2 of the in the side wall of the cylinder 3 of the compressor at such. a point that they will be uncovered when the piston 2 is at the lower end of its stroke, and thus permit the gas to flow into the cylinder from a suction chamber 5 to which a supply pipe 6 leads, said suction chamber being preferably formed in an integral portion 5 on the side of thecylinder 3. A discharge valve 7 is arranged at the upper end of the cylinder 3, which valve is normally held seated by means of a spring 8 that is interposed between the valve and the head 9 of the cylinder 3. The crank case of the compressor is Patented $ept. i2, 3.291%.

preferably provided with removable heads 1 I v 10, one of which is equipped with a stuiiingthrough which water is supplied by a pipe box, through which the crank shaft 11 of the compressor passes, said shaft also bemg partly aupported by a bearing 12 on the base A of the machine. vVhen the piston 2 moves downwardly on its return stroke, the partial vacuum that is created in the cylinder 3 above the top of thepiston, causes the gas to rushinto the cylinder through the ports 4 as soon as the piston uncovers said ports. On the succeeding compresslon stroke of the piston this charge of gas is compressed and forced out of the cylinder when the automatically-operating discharge valve 7 opens, thegas escaping through a pipe or duct 13, shown in Fig. 2, that leads into the condensing chamber C wherein said gas is condensed and converted into a hqmd state. The condensed liquid collects in the bottom of the condensing chamber C so that said chamber also acts as a receiver or holder for the liquid. The liquid is conducted away from the condensing chamber C by means of a pipe 14 that leads to an expanslon valve,,not shown.

In the preferred form of our invention as herein shown, the condensing chamber is formed by a cylindrical-shaped or drum shaped member of steel, wrought-iron, of other suitable material, that is provided at one end with an integral head 15, the other end of said member being screwed into a head or cap-piece 16 that is detachably connected to the base A of the machine by means of bolts or other suitable fastening devices 17, as shown in Fig. 1. The ipe 13, through which the gas is conducted condensing chamber, is screwed into an opening 18 in the removable head 16 of the condenser, and the outlet-pipe 14, through which the condensed liquid is conducted away from the condenser, is also screwed into saidremovable head. A liquid gage- 19 is connected to the removable head 16 of the condenser so as to show the level of the liquid in the condenser, and a high pressure gage 20 is also mounted on said head 16, as shown in Figs; 2 and 5, to indicate the pressure in the condenser.

The space between the member C and the walls of the base A forms a water-jacket 21 that is tapped into the base, as shown 1n Figs. 3 and 4, and the pipe 22 that is tapped into-the upper, side of the base- A, serves to connect the water-jacket ofuthe condensing chamber with a. water-jacket at the upper end of the cylinder? of the compressor which is preferablyhformed by means of-a shell 23 that reconnected to the'cylmder by means of a stud 2d and nut 25, as shown'in arranged at the-{bottom of the condensing chamber (Lea-1d valve being mounted in a 1 valve casing 32? on the remcvable'head 16 to the An oil-drain valve is preferably drain-pipe 28.

By combining the compressor and the condenser so that they form a single unit, we obtain a small self-contained refrigerating machine that is particularly adapted for household use, the condensing chamber being completely incased by the base of the machine, and cooperating with said base to form a water-jacket that surrounds the condensing chamber. The machine can be made in very small sizes, owing to the elimination of the suction valve, and as the entire machine comprises comparatively few parts which are of simple construction, the machine can be manufactured at a low cost, and is not apt to get out of order when in use.

In addition to the desirable features above mentioned, a machine of the construction above described insures rapid condensation of the gas, owing to the fact that the gas that enters the condenser comes in contact with the surface of a comparatively large body of liquid in the lower part of the con densingchamber, the condensing chamber serving as a holder or receiver for the condensed liquid.
